' Application led January 28, 1916. Serial No. 74,735.

the State of New York, have invented a certain new and usefulImprovement in Coated Products, and do hereby declare that the followingis a full, clear, and exact description thereof.

My invention relates particularly to sheets of coated'materials, such aswoven fabrics,

artificial leather, paper and leather, but es-k pecially to coatedartificial leather.

Ilhe object of my invention is to provide' a coated fabric in the formof a sheet, which is of -such a nature that it may be readily caused toadhere to other surfaces. More particularly, the object of my inventionis to provide a product of this character, which is especially useful inbookbinding,V and to which gold-leaf and paper may be readily caused toadhere. A further object of my invention is to provide a pyroxylincoated productwhich, under the influence of heat or water or some othersolvent, becomes readily adherent to substances or materials applied tothe surface thereof.

While my invention is capableof being carried out in many differentWays, for the purpose of illustration l shall describe only one examplethereof hereinafter.

'In the drawings, the single gure showsv the perspective view of afabric treated according to my invention.

My invention may, for example, be carried out as follows: Any suitablebacking, which may be awoven "fabric, paper, or leather, and which mayor may not already have been coated with one or more coats of variousmaterials, but which is Ipreferably an artificial leather formed on awoven fabric backing by applying one or more coats of a pyroxylinsolution containing 10.02. by weight of pyroxylin, 1" gal. of solvent,comprising 15% .of amyl acetate and 85% of wood alcohol or 50% amylacetate and 50% benzene, and which may contain any suitable pigment, isprovided with a top coating containing pyroxlyn 10 oz. by weight, 1 gal.of a solvent comprising 15% amyl acetate and 85% wood alcohol or 50%amyl acetate and 50% of benzene, and one pound of a fish glue solutioncontaining 50% of glue and 50% -of water, to which may be added, if desired, one oz. of birch tar or some similar essential oil to remove theodor of the fish glue and give the product an odor the same as that ofRussian leather. Any other suitable adhesive material mayalso be addedto the composition in this coating either in addition to or insubstitution for the fish glue solution, as for example gums, such as tsandarac and shellac. rlhe coating or coate ings above referred to maybe applied in Vany suitable way, as for example, by the use of a doctorblade, rolling, brushing, or flowing, and the coating containing theadhesive material may be applied before or'after embossing. f A productmade in this manner, will readily adhere to materials placed upon thesame under the influence of heat or moisture or both. The coated productthus produced is especially suitable for use in bookb-inding asgold-leaf Will readily adhere to thepsame when applied by a letteringtool, which has been previously heated to a mod erate degree in theusual way. It Will also readily adhere to paper, as for example, a

paper which is applied to the inner faces mixture of pyroxylin and anadhesive, por? -tions of said adhesive being exposed at the surface ofthe coated. product.
